Abstract

Silicon is an interesting candidate to be used as an anode material for the next generation Li-ion battery. Silicon due to its high specific capacity (mAh/g) among the known anode materials for Li-ion battery is expected to fulfill the existing demands of the market. It is also abundant and cheap. Unfortunately, significant breaking impact during lithiation procedure of lithium in continuous charge-release process that causes structural degradation, in this way losing specific capacity and contact amongst electrolyte and cathode. To overcome the results noteworthy achievements have been made in creating silicon nanosheets. Thermic reduction of SiO2 can be done by few known methods that includes carbothermal, magnesiothermic, aluminothermic, and calciothermic lessening. In this work, we have synthesized silicon nanosheets by using magnesiothermic reduction. Magneisothermic reduction of sand by furnace heating was found successful to produce silicon nanosheets at 600°C. According to results, we have observed that the silicon nanosheets have a leaf-like sheet morphology ranging from a few ten to hundred nanometer.
